this does not guarantee that *all* of the above assembly source files were tested): (1) Ia32: tested a 32-bit Fedora guest, with the steps described in . Result: PASS. (2) Ia32X64: testing based on the same Wiki article. (2a) 64-bit Fedora guest. Result: PASS. (2b) 64-bit Windows 8.1 guest. Result: PASS. (3) X64: more-or-less based on the same Wiki article (but this build does not include the SMM driver stack). Used a 64-bit Fedora guest. Result: PASS. Thus, NASM 2.13rc10 looks fine to me. A big "thank you" to the NASM development team! Laszlo
